A. Unless otherwise directed by the state or defendant, subpoenas shall be served by domiciliary service, personal service, or United States mail as provided in Paragraph B. Personal service is made when the sheriff tenders the subpoena to the witness. Domiciliary service is made when the sheriff leaves the subpoena at the dwelling house or usual abode of the witness with a person of suitable age and discretion residing therein as a member of the domiciliary establishment of the witness.

B.(1) The criminal sheriff for the parish of Orleans and all other sheriffs throughout the state may serve all subpoenas directed to him to be served by mailing the said subpoenas in the United States Post Office, by either certified mail, return receipt requested, or first class mail to the addressee at the address listed on the subpoena.

(2) Service by first class mail shall include a request that the enclosed return form be signed by the addressee and mailed to the sheriff. If a signed return is not received by the sheriff, the subpoena shall be served by domiciliary or personal service as provided in Paragraph A.

(3) Service by mail shall be considered personal service if the certified return receipt or the return form is signed by the addressee. Service by mail shall be considered domiciliary service if the certified return receipt or the return form is signed by anyone other than the addressee.

C. The criminal sheriff of the parish of Orleans and all other sheriffs throughout the state are hereby authorized to make service of subpoenas to law enforcement officers through the law enforcement officer's ranking officers or their designated representative, which, upon service thereof, shall have the same legal effect as if domiciliary service had been made upon the law enforcement officer named therein. This service shall be made at the district stations or departmental headquarters of said law enforcement agency. Service may consist of individual subpoenas or may consist of lists which include officer's name and badge number, case title, name of court, and date of commanded appearance. Such lists may be served by the sheriff or his deputies by means of electronic transfer to printing devices located in the district stations or departmental headquarters. The ranking officer, or his designated representative, shall sign for such subpoenas or indicate receipt by electronic verification code, and shall be required to notify the law enforcement officer named therein of receipt of the subpoenas or list.

D. This type of subpoena service shall be known as departmental subpoena service of law enforcement officers, and shall not be construed to replace domiciliary or personal service for said officers, but shall be an additional method of service.
